Carl Bernstein may not be a household name among the average American, but in journalism circles, he is an icon. Bernstein is the reporter that broke the Watergate story that eventually brought down President Richard Nixon.

Bernstein was also recently involved with CNN in the reporting on classified information to Obama and Trump that the latter mistook for a Buzzfeed report, causing him to embarrass himself at his press conference on Wednesday by shouting and silencing a CNN reporter.

Bernstein had some strong words for Kellyanne Conway on Wednesday night on air with Anderson Cooper. He called Conway Trump’s “Propaganda Minister” during the exchange below:

ANDERSON COOPER (HOST): “And Carl, I should just point out because you were involved in this reporting, CNN is not reporting what’s in the BuzzFeed — all those — all the things that they talk about. We have not been discussing this.”

CARL BERNSTEIN: “Not in the least, and let’s talk about what reporting is. It’s the best obtainable version of the truth. That’s what that story is, the best obtainable version of the truth is that the chief intelligence officials of the United States of America saw this material, thought that it deserved investigation, thought that it ought to be brought to the attention of the president of the United States and to the president-elect. That is the best obtainable version of the truth.”

“And another thing about anonymous sources, one of the great anonymous sources of our era is Kellyanne Conway. She does it every day, she has been an anonymous source for the last ten months particularly during this campaign when it suits her, and it’s time to talk about what we do as journalists, and what propaganda ministers do, and that is what she is, is a propaganda minister.”

“And what we’ve seen here tonight is a deconstruction of the journalistic process. And we did our work and you can deconstruct it, and it comes down to, look, the chief officials of the United States intelligence community believed they had something urgent enough to bring to the attention of the president, and the president-elect of the United States. That is a story.”

CNN is getting ready for an all-out 1st amendment battle with the Trump team, and shots have been fired from both sides already. This administration must not be allowed to continue its onslaught against a free press and freedom of speech.
